. SPECIFICATION forming part of Letters Patent No. 601,521, dated March 29, 1898.

Application filed July 9, 1897. Serial No. 644,024:- (No model.)

To all whom it may concern:

Be it known that I, JOHN ERNST MELCHER, of \Visner, in the county of Cumin g and State of Nebraska, have invented a new and Improved Ejector, of which the following is a full, clear, and exact description.

The invention relates to dredging, placermining, andlike apparatus used for loosening and removing sand, mud, gravel, &c., from rivers and other places; and the object of the invention is to provide a new and improved ejector which is simple and durable in construction, very effective in operation, and arranged for readily loosening the material and discharging the same at any desired place.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a sectional side elevation of a modified form of the same; and Figs. 3 and 4 are side elevations, respectively, of the devices illustrated in Figs. 1 and 2,showing them applied and also showing iron pipes for connecting the inlet-pipes with the pump.

The improved apparatus is provided with a supply or inlet pipe A, connected at its upper end by a hose B with a force-pump of any approved construction to cause a stream of water to pass through the hose B into and down the supply-pipe A. The lower end of the pipe'A is connected with a nozzle-casing C, supporting a short pipe 0, containing a nozzle D, extending upwardly, as is plainly indicated in Fig. 1, to discharge Water under pressure in a vertical direction into a casing E, forming the lower end of a discharge-pipe- F, provided at or near its top with a gatevalve G for opening or closing the saidpipe F. The casing E is provided with a vertical pipe E and with a downwardly-leading extension E connected with a suction-pipe H, arranged alongside the casing O, as is plainly indicated in the drawings.

The lower end of the casing O is provided with a short pipe 0 containing a nozzle D, similar to the nozzle D but normally closed by a plug I, the said nozzle extending downwardly to discharge water through the pipe 0 into a cutter J, screwed on the lower end of the pipe C The cutter J is provided with teeth J, and similar teeth H are formed on the suction-pipe H, so that when the apparatus is turned the said cutters loosen the ground in the immediate vicinity.

When the several parts are in the position shown in Fig. 1 and the valve G is open, then the water under pressure from the force-pump, passing down the pipe A into the casing O,

finally passes up the pipe 0 and the nozzle D to eject the water in an upward direction through the vertical pipe E of the casing E into the pipe F, so that a suction is created in the suction-pipe ILand consequently the sand, mud, gravel, and water pass up the said pipe H and casing E to be forced by the action of the water under pressure upward through the pipe F to a place of discharge.

When it is desired to loosen some of the ground, the valve G is closed and the plug I is removed from the nozzle D, so that part of the water under pressure passes up through the nozzle D andthrough suction-pipe H and part of the water can pass down through the said nozzle D and out of the cutter J directly into the ground, so as to loosen the same and cause some of the loosened material to rise up in the water along the pipes A and F. When a sufficient amount of ground has been removed for the apparatus-to take its proper place in the material, then the .valve G is opened, so that the suction of the material again begins in the pipe H by the action of the Water passing through the nozzle D, for the purpose above explained.

By reference to Fig. 1 it will be seen' that the nozzle D is considerably smaller in its opening than the nozzle D, so that the bulk of the water will be dischargedthrough the nozzle D when the nozzle D is open and the valve G is open, as above explained.

The pipe A may be connected by iron pipes B instead of flexible hose with the forcepump,as shown in Figs. 3 and 4; but in this case joints or L-sections and couplings are used to allow the pipe to move sidewise up or down, so that the apparatus can be moved in all directions from the pump. The L-sections previously referred to are connected with suitable unions and loose joints. If the ejector is lowered in the ground, then the pipe A can be swung to the side of the suction-pipe H to render theejector very compact to follow the cutters readily in the ground, the whole turning on the casing 0.

As illustrated in Figs. 2 and 4, the nozzlecasin g C is provided with a short pipe or nipple O 011 which is secured a nozzle D made L-shaped and having its mouth in alinement with the cutters H at the lower end of the suction-pipe H The nozzle D may be turned, however, in any other desired direction. This arrangement is more especially used when the soil is gummy and needs a strong pressure of Water to wash the soil toward the lower end of the suction-pipe H.

The openings in the cutters are somewhat less than the pipes, so that a stone passing the cutters J and H is not liable to clog the pipes.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An ejector, comprising a supply-pipe for connection with a force-pump, a casing at the lower end of the pipe and provided with an upwardly-projecting nozzle and a downwardlyprojecting nozzle, the downwardly-projecting nozzle being of smaller area than that of the upwardly-projecting nozzle, a discharge-pipe in alinement with the upwardly-projecting nozzle, and a suction-pipe opening into the lower end of the discharge-pipe, substantially as described.

2. An ejector, comprising a supply-pipe for connection with a force-pump, a casing at the lower end of the supply-pipe and provided with oppositely-proj ectin g nozzles, one proj ecting upwardly and the other downwardly, discharge-pipes projecting from the casing and into which the nozzles project, the lower pipe being provided with cutters, and the upper one With a valve, and a suction-pipe connected with the upper dischargepipe and provided with cutters at its end substantially as described.

3. An ejector, consisting of a supply-pipe for connection witha force-pump, a casing at the lower end of the pipe and provided with oppositely-projecting nozzles, one projecting upwardly and the other downwardly, the upper nozzle being of greater area than the lower one, a casing into which the upper nozzle projects, a discharge-pipe secured to the lastnamed casing and provided with a valve, a suction-pipe also secured to the last-named casing and provided with cutters at its end, and a pipe secured to the first-named casing and into which the lower nozzle projects, said pipe being provided with cutters, substantially as herein shown and described.

JOHN ERNST MELCHER.
